  • Elon Muskk:

    XML and JSON are both data formats that are widely used for storing and transporting data, particularly over the internet. Here's a detailed explanation of each, followed by a translation into Chinese. --- XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML is designed to store and transport data. It is derived from SGML (Standard Generalized Markup Language), but is more straightforward and user-friendly. XML tags are user-defined and can be created to represent any kind of data or document structure. XML files are text-based and can be created and edited with any text editor. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is based on a subset of the JavaScript language, but it is language-independent and can be used with many programming languages. JSON is often used for transmitting data in web applications, as it is supported natively by many web browsers and server environments. It is particularly popular for use with AJAX in web pages to transmit data to and from the server. Both XML and JSON are used for similar purposes, but they have different structures and uses. XML tends to be more verbose and is often used in complex data structures where document validity is important. JSON, on the other hand, is more concise and is typically used when efficiency and ease of use are more important than document validity. Here's the translation in Chinese: --- XML (可扩展标记语言) 是一种定义了一套规则的标记语言,用于编码文档,使其既适合人类阅读,也适合机器阅读。XML 旨在存储和传输数据,它源自 SGML (标准通用标记语言),但更为直接和用户友好。XML 标签由用户定义,可以创建以代表任何类型的数据或文档结构。XML 文件是基于文本的,可以用任何文本编辑器创建和编辑。 JSON (JavaScript 对象表示法) 是一种轻量级的数据交换格式,易于人类阅读和编写,也易于机器解析和生成。它基于 JavaScript 语言的一个子集,但与语言无关,并且可以与许多编程语言一起使用。JSON 常用于在网络应用程序中传输数据,因为它被许多网络浏览器和服务器环境原生支持。它特别适用于与 AJAX 一起在网页中传输数据到服务器和从服务器传输数据。 XML 和 JSON 都用于类似的目的,但它们有不同的结构和用途。XML 往往更加冗长,通常用于复杂的数据结构,其中文档的有效性很重要。而 JSON 则更加简洁,通常在效率和易用性比文档有效性更重要时使用。 read more >>
